SerialGhost TimeKeeper DB9 16GB - Compact RS232 Logger and Serial Logger with 16GB Flash Drive and Time-stamping

The SerialGhost TimeKeeper is a compact RS-232 and serial bus logger with 16GB of memory and a time-stamping module. It can acquire data from a single serial data source, or tap onto a bi-directional serial bus. The SerialGhost can operate as USB flash memory for easy access to logged data. It''s packed with features such as dual port configuration or virtual COM port mode with data streaming and a proprietary command set.

Data logging made simple

The SerialGhost is a compact asynchronous serial logger, capable of recording RS-232 data streams from devices like printers, GPS receivers, terminals, keyboards, mice, barcode scanners etc. Connect the device either to a single serial source, or in-line on a serial bus. Connect 5V DC power using the side USB-B connector. The SerialGhost will immediately start logging all data available on the bus, both upstream and downstream (RX and TX). No software or drivers are required.

Easy access

To view the recorded data, the SerialGhost may be switched to flash drive mode. Connect to a computer using a USB-B cable, press the side button, and the SerialGhost will pop up as a removable drive, containing a file with logged data. The log file will be interleaved with time and date-stamps. The flash drive may also be used to configure the device, such as baudrate, parity bits, start/stop bits, etc.

Dual port

The SerialGhost family of devices has two RS-232 input ports, responsible for data acquisition from up to two sources. Both ports can share a common configuration, or may be configured independently using dual port mode. In this mode two separate settings may be used for the baud rate, number of bits, stop bits, and parity.

SerialGhost TimeKeeper DB-9 - Multiple modes

Multiple modes

The SerialGhost family is packed with features, such as the capability to act as a USB removable flash drive, or USB Virtual COM port. In flash drive mode, a log file is available with all acquired data. Virtual COM port mode can be used to live-stream the captured data, or to communicate with the device using a proprietary command set.

Date and time-stamping

The built-in real-time clock will keep track of the time and date independent if the computer is turned on or not. This is possible thanks to the internal battery, with a guaranteed lifetime of over 10 years. Time and date stamps with millisecond granularity will get inserted in the log file while the logger is capturing data.
